       * 
       * 功能需求：
	   * 
       * 1. 基本渲染
	   * (1)立刻发送请求获取数据created
	   * (2)拿到数据，存到data的响应式数据中
	   * (3)结合数据，进行渲染 v-for
	   * (4)消费统计 =>计算属性
       * 2. 添加功能
	   * (1)收集表单数据,v-model
	   * (2)给添加按钮添加点击事件，发送添加请求
	   * (3)需要重新渲染
       * 3. 删除功能
       * 4. 饼图渲染
	   * (1)初始化一个饼图echarts.init，mounted钩子实现
	   * (2)根据数据实施更新视图
